“…The interactive effect of tillage and straw returning were significant for all size of aggregates except (1-2 and 0.5-1.0 mm) at 0-20 cm and except for 2-5 . Alike to these findings that macro-aggregate (> 0.25 mm) proportion were significantly changed by NTS at upper soil layer (0-20 cm) but decreased at lower depth (Liu et al, 2014;Xin et al, 2015). In this study, NTS treatment significantly increased macroaggregates (> 0.25 mm) at the 0-20 cm depth and increased microaggregates (< 0.25 mm) at 20-40 cm depth in comparison with CT treatment.…”

No-tillage and straw returning are important practices for preserving and improving soil quality for the sustainable management system. The experimental field was established in 2007 with conventional tillage (CT), conventional tillage with straw returning (CTS), no-tillage (NT), and no-tillage with straw returning (NTS) practice in rice (Oryza sativa L.)-rape (Brassica napus L.) cropping system. The soil samples were collected in 2013-2015 from 0-20 and 20-40 cm depth to investigate the effects on soil organic C (SOC), water-stable aggregation (> 5, 5-2, 2-1, 1.0-0.5, 0.25-0.5, and < 0.25 mm), and their stability in paddy soil of the central China. In the last year (2015), the integrative use of no-tillage and straw returning significantly increased SOC content and contribution of the macroaggregates in 0-20 cm and microaggregates in 20-40 cm depth. Compared with CT, SOC content, mean weight diameter (MWD), geometric mean diameter (GMD), and fractal dimensions (FD) under NTS were increased 25%, 21%, 19%, and 12%, respectively, in the 0-20 cm depth. In 20-40 cm depth, the soil micro-aggregates were higher under CTS treatment. Percentages of macroaggregates and microaggregates under NTS were increased 60% and 40% in the 0-20 cm depth. The SOC had positive linear relationship with MWD, GMD, > 5, 2-5, 1-2, and 0.25-0.5 mm aggregates. Thus, long-term combine use of NT with straw returning practices significantly improved SOC and water-stable aggregation. No-tillage and straw returning appeared to be promising and sustainable strategies to conserve SOC sequestration and stable soil aggregates in rice-rape cropping system.

“…Depois da adoção de 12 anos de plantio direto os estoques de C retornaram para os níveis daqueles sob vegetação natural, com nenhuma diferença significativa entre os estoques de C entre cerrado e PD12 (Siqueira . Liu et al (2013) Ressalta-se que em sistemas menos perturbados pelo preparo do solo, como o plantio direto (PD), após a decomposição dos resíduos vegetais, os estoques de carbono orgânico total (COT) podem aumentar na camada superficial. Neste sentido, Leite et al (2010) constataram que o estoque de carbono na camada 0-20 cm em Latossolo Vermelho-Amarelo do cerrado piauiense foi maior no PD6, intermediário no PD2 com o PD4 não diferindo desses e menor no PC e na floresta nativa (FNC).…”

Estoque de carbono e atributos físicos de um Latossolo em cronossequência sob diferentes manejos 1 Karina de V. Rossetti 2 & José F. Centurion 3 DOI: http://dx.doi. org/10.1590/1807-1929/agriambi.v19n3p252-258 R E S U M O Propôs, neste trabalho, determinar o efeito do sistema plantio direto (SPD) sob diferentes anos de implantação e do preparo convencional (SPC) cultivados por dois anos agrícolas, com soja e milho, sobre os estoques de carbono e atributos físicos de um Latossolo Vermelho em comparação com a mata nativa. O delineamento foi inteiramente casualizado, em parcelas subdivididas (cinco tratamentos e três camadas), com quatro repetições. Os tratamentos em 2008/09 foram: SPD com 5 (SPD5), SPD com 7 (SPD7), SPD com 9 (SPD9) anos de implantação, SPC e uma área de mata nativa (MN). Os tratamentos se estenderam para o ano de 2009/10, assim identificados: SPD6, SPD8, SPD10 e SPC e MN; as camadas de solo estudadas foram: 0-10, 10-20 e 20-30 cm. Os resultados obtidos mostraram que a maioria dos tratamentos manteve o teor do estoque de carbono (EC) durante a transição da camada superficial para a subsuperficial. O maior EC foi mais pronunciado na camada superficial na qual os SPD9 e SPD10 foram os mais relevantes em comparação com os demais sistemas conservacionistas. Carbon stock and physical attributes of an Oxisol in chronosequence under different managements practices A B S T R A C TThe aim of this study was to determine the effect of the no-tillage planting systems (NT) under different years of implantation and of conventional tillage, growing soybeans and maize for two crop years, on carbon stocks and physical attributes of a Red Oxisol in comparison to native forest. A completely randomized design with split-plots (five treatments and three layers) was used, with four replications. The treatments in 2008/09 were: NT with 5 (NT5); NT with 7 (NT7); NT with 9 (NT9) years of implantation, conventional tillage (CT) and a native forest area (NF). The treatments extended to the year 2009/10, identified as: NT6, NT8, NT10 and CT and NF; the studied soil layers were: 0-10, 10-20 and 20-30 cm. The results obtained showed that most of the treatments maintained the carbon stock content (CS) during transition from the surface layer to the underground layer. CS was more pronounced in the surface layer and, within it, the NT9 and NT10 were the most relevant in comparison to the other conservationist systems.Palavras-chave: matéria orgânica do solo plantio direto sistema convencional

“…According to Leinweber et al (2001), an intensive plow tillage stimulates the microbiological decomposition of post-harvest residue, thus increasing the content of DOM. Andruschkiewitsch et al (2013) and Liu et al (2014) claim that plowless tillage combined with an adequate plant selection in crop rotation can lead to an increase in DOC in soil. Liu et al (2014) reported a twofold higher DOC content in the 0-5 cm soil layer with plowless tillage, as compared with the soil with plow tillage.…”

Purpose The aim of this paper has been to determine the seasonal changes in the content of dissolved organic matter (DOM) in the soils under agricultural use based on assaying changes in dissolved organic carbon (DOC) and dissolved nitrogen (DNt) as well as determining the factors which can define the DOM in soils. Materials and methods The research has involved the soils under agricultural use sampled in the Kujawsko-Pomorskie province (Poland). Phaeozems and Luvisols were sampled from the depth of 0-30, 30-60, and 60-100 cm, November 2011 through September 2013, in November, March, May, July, and September. The soil samples were assayed for the grain size composition, pH, dry weight content, content of total organic carbon, and total nitrogen. Dissolved organic matter was extracted with 0.004 mol dm 3 CaCl 2 ; in the DOM extracts, the content of dissolved organic carbon (DOC) and dissolved nitrogen (DNt) were assayed. The research results were statistically verified. Results and discussion It has been demonstrated that in the first year of research, the content of dissolved organic carbon in the soils was changing throughout the year. The highest differences in the content of that carbon fraction occurred across the soil sampled in autumn and the soil sampled in spring. In the second year of research, an inverse dependence was noted. DOC was migrating to deeper layers of the soil profile; yet, the migration got more intensive in summer. The content of dissolved nitrogen was not changing significantly throughout the year. Higher DNt content in the surface layer, in general, resulted in a higher content of dissolved nitrogen in deeper profile layer, which could have been due to leaching of the nutrient deep down the soil profile. Conclusions The content of dissolved organic carbon was significantly related to the content of total organic carbon and total nitrogen. Significant changes in the content of dissolved forms of nitrogen were reported in the profile of Phaeozems due to mineral fertilization and irrigation. The soils where irrigation and higher nitrogen rates had been applied demonstrated a higher content and share of soluble forms of nitrogen, as compared with the soils non-irrigated and the soils where lower nitrogen rates had been supplied.
